Facile synthesis of ultra-small rhenium nanoparticles

摘要

Ultra-small monodisperse rhenium nanoparticles (Re NPs; ca. 1.0-1.2 nm) were easily prepared by reducing the organometallic complex [Re_2(C_3H_5)_4] under a dihydrogen atmosphere under mild reaction conditions (3 bar H_2; 120 ℃). The particles can be stabilized by a ligand, hexadecylamine, or a polymer, polyvinylpyrrolidone and accommodate surface hydrides.
